Do you have a subscription with rate limitations?  The PGW (router = which enforces the limit) is a lot more latency friendly than if you are ra= dio limited.  So it may be beneficial to have a "slow" subsc= ription rather than "free speed" then it comes to latency.  Slow meaning lower subscrption rate than radio rate.


Also would be interesting to see separate tests for upstream and downstr= eam, as the issues and implementations are different in each direction.
